Beginner Node.js - Part 2: Node.js Basics

In Part 1, I briefly explained what Node.js is and showed how to get it installed on the 3 major operating systems, Windows, OSX, and Ubuntu. In Part 2, I want to focus more on what Node.js is and what concepts one would need to understand in order to develop effectively using Node.js. Although it is just JavaScript, there are some additional concepts that make JavaScript effective on the server.
